Meta launches Muse Ember, its smallest reasoning model, at $0.10 per million input tokens

What happened

The company has launched Muse Ember, its smallest reasoning model to date, on the Meta Model API (the interface one piece of software uses to talk to another). What Meta actually shipped Muse Ember slots in at the bottom of the Muse lineup, a family of multimodal (able to work with more than one kind of input, such as text and images) reasoning models built by Meta Superintelligence Labs.

The price tag is the headline act: $0.10 per million input tokens and $0.50 per million output tokens . In a market where AI bills can balloon quickly, that is a deliberate pitch to developers who watch every line on their cloud invoice.

Ember charges $0.10 for every million tokens fed into it. It charges $0.50 for every million tokens it produces in response.

The broader Muse family is designed around tool use and handling mixed inputs. That contains text, images and audio, which means the models are meant to do more than chat.

Ember sits beneath larger siblings like Muse Spark and Muse Wonder. Those bigger models are aimed at heavier workloads, the kind of jobs where raw capability matters more than cost per query.
